Monga tonse tikudziwa, PCB ndiye "mlatho" wolumikizira zida zamagetsi ndipo ndiye gawo lalikulu muzinthu zamagetsi. Ili ndi ntchito zosiyanasiyana, kuphatikizapo zamagetsi zamagetsi, zamagetsi zamagalimoto, kulumikizana, zamankhwala, ntchito zankhondo, ndege ndi zina zotero. Masiku ano, zamagetsi zamagetsi zamagalimoto ndi zamagetsi zamagalimoto zikukula mwachangu kwambiri ndipo zimakhala malo ogwiritsira ntchito kwambiri. Pakadali pano, kuwotcherera kwa PCB kwakopa chidwi chachikulu kuchokera kwa opanga ma PCB. Ndiye, ndi mitundu yanji ya PCB yomwe makina owotcherera a laser angagwire ntchito? Tiyeni tiwone mwatsatanetsatane pansipa.
1. Chinthucho chiyenera kusunthidwa
Zimatanthauza kuti kutentha koyenera, chitsulo chomwe chikufunika kusungunuka ndi chitsulo chosungunula zimatha kusakanikirana kuti zikhale ndi khalidwe labwino la alloy. Si chitsulo chilichonse chomwe chili ndi kuthekera kosungunula bwino. Kuti chitsulocho chikhale chosungunula bwino, ogwiritsa ntchito amatha kusungunula chitsulocho kapena kuchiyika pa chitsulocho kuti apewe kusungunuka kwa pamwamba pa chitsulocho.
2. Chinthucho chiyenera kukhala choyera pamwamba pake
Kuti pakhale chitini chosungunula ndi zinthu zomwe zikuyenera kusungunuka, pamwamba pa chinthucho payenera kukhala paukhondo. Ngakhale pazinthu zabwino zosungunula, filimu ya okosijeni kapena banga la mafuta likhoza kuchitika pamwamba pa chinthucho. Chifukwa chake, kuti zitsimikizire kuti chosungunula chili bwino, pamwamba pa chinthucho payenera kukhala paukhondo.
3. Gwiritsani ntchito ufa woyenera wa scaling
Cholinga cha ufa woyezera ndikuchotsa filimu yoyezera pa chinthu chomwe chikuyenera kuwotcherera. Njira zosiyanasiyana zoyeretsera ziyenera kugwiritsa ntchito ufa woyezera wosiyanasiyana. Pazowunikira zamagetsi monga PCB, rosin iyenera kugwiritsidwa ntchito ngati ufa woyezera kuti zitsimikizire kudalirika kwa kuwotcherera.
4. Chinthucho chiyenera kutenthedwa kufika kutentha koyenera
Ngati kutentha kwa welding kuli kotsika kwambiri, alloy singathe kupangidwa. Ndipo ngati kutentha kwa welding kuli kokwera kwambiri, welding flux idzakhalabe mu mkhalidwe wosakhudzana ndi eutectic, zomwe zidzachepetsa ubwino wa welding flux ndipo pazochitika zoyipa kwambiri, pedi pa PCB idzatsika.
5. Kuwotcherera kumafuna nthawi yoyenera
Nthawi yowotcherera imatanthauza nthawi yomwe imagwiritsidwa ntchito mu mankhwala ndi zochitika zakuthupi mu ndondomeko yowotcherera. Pambuyo posankha kutentha kwa kuwotcherera, ogwiritsa ntchito ayenera kusankha nthawi yoyenera yowotcherera kutengera mawonekedwe, mtundu ndi mawonekedwe a zinthu zomwe zikuyenera kuwotcherera. Ngati nthawi yowotcherera ndi yayitali kwambiri, zigawo kapena zigawo zowotcherera zimakhala zosavuta kuwonongeka. Nthawi zambiri, malo aliwonse sayenera kutenga masekondi opitilira 5 nthawi imodzi.
Kuti makina opukutira laser a PCB akhale abwino kwambiri, amafunika kuziziritsidwa bwino ndi makina opukutira laser. S&A Teyu yakhala ikugwiritsa ntchito makina opukutira a mafakitale kwa zaka 19 ndipo imatha kupereka makina opukutira a mafakitale amitundu yosiyanasiyana ya makina opukutira laser. Makina opukutira ozungulira ali ndi mphamvu yosavuta kugwiritsa ntchito, yosakonzedwa bwino, yokhala ndi nthawi yayitali yogwira ntchito, komanso yodalirika kwambiri. Mphamvu yoziziritsira imakhala kuyambira 0.6KW mpaka 30KW, zomwe zingakwaniritse zosowa zoziziritsira za ogwiritsa ntchito osiyanasiyana. Ngati simukudziwa mtundu wa makina opukutira ozungulira omwe mungasankhe, ingotumizani imelo ku marketing@teyu.com.cn
